The Messenger of Allah ﷺ said, "Silver is exchanged with silver, and gold is exchanged with gold, equally with equal."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْفِضَّةُ بِالْفِضَّةِ وَالذَّهَبُ بِالذَّهَبِ مِثْلًا بِمِثْلٍ
The Messenger of Allah ﷺ said, "Silver is exchanged with silver, and gold is exchanged with gold, equally with equal."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْفِضَّةُ بِالْفِضَّةِ وَالذَّهَبُ بِالذَّهَبِ مِثْلًا بِمِثْلٍ
This hadith has been narrated on the authority of Abu Sa'id al-Khudri (Allah be pleased with him) through another chain of transmitters.
قَالَ رَسُولُ اللَّهِ ﷺ الذَّهَبُ بِالذَّهَبِ مِثْلاً بِمِثْلٍ فَذَكَرَ بِمِثْلِهِ
'(Sell) silver for silver, gold for gold, barley for barley, wheat for wheat, like for like."
عَنِ النَّبِيِّ ﷺ قَالَ الْفِضَّةُ بِالْفِضَّةِ وَالذَّهَبُ بِالذَّهَبِ وَالشَّعِيرُ بِالشَّعِيرِ وَالْحِنْطَةُ بِالْحِنْطَةِ مِثْلاً بِمِثْلٍ
[Machine] Narrated by the Prophet Muhammad ﷺ , he said, "Gold is bought with gold, silver is bought with silver, and paper money is bought with paper money, like for like, hand in hand. Whoever increases or is increased has indulged in riba (usury)."
عَنِ النَّبِيِّ ﷺ قَالَ الذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ وَالْوَرِقُ بِالْوَرِقِ مِثْلًا بِمِثْلٍ يَدًا بِيَدٍ مَنْ زَادَ أَوْ ازْدَادَ فَقَدْ أَرْبَى
"The Messenger of Allah said: 'Gold for gold, weight for weight, like for like; and silver for silver, weight for weight, like for like. Whoever gives more or takes more has engaged in Riba."' (Using translation from Nasāʾī 4569)
عَنِ النَّبِيِّ ﷺ قَالَ الْفِضَّةُ بِالْفِضَّةِ مِثْلًا بِمِثْلٍ وَزْنًا بِوَزْنٍ وَالذَّهَبُ بِالذَّهَبِ وَزْنًا بِوَزْنٍ مِثْلًا بِمِثْلٍ فَمَنْ زَادَ فَهُوَ رِبًا
"الْفِضَّةُ بالفِضَّةِ، والذَّهَبُ بالذَّهَب، والشَّعِيرُ بالْشَّعِيرِ، والْحِنْطَةُ بالحنطة مِثْلًا بمِثْلٍ" .
